Intergenerational effects on fertility Theory and evidence from Israel

On the assumption that genetic inheritage and experience during adolescence influence the taste for children, the characteristics of a couple's parents may be used to improve on the explanation of fertility which can be obtained from variables that only refer to the couple itself. We find that in Israel fertility depends positively on the mother's siblings and negatively on the grandfathers' wage, but apparently does not depend on the father's siblings. Since fertility also depends positively on the mother's predicted wage, the number of children is positively related to improvements in the economic achievements from one generation to the next.
